Lighting setups
Control light direction, number, and color so forms keep consistent highlights, shadows, and color shifts.
What it is
Lighting setups describe how light reaches a subject: from behind, above, below, from several directions, or in different colors. Each setup requires you to place light sources and track their effects.
You can identify a setup from a brief or reference, such as top light with a warm rim from behind and cool fill from the front. You keep that structure consistent across a painting or sequence, linking highlights, shadow edges, and color shifts to specific lights.
Changing the setup changes the form. Backlighting creates a mostly silhouetted subject with a thin lit edge. Top lighting darkens downward-facing planes and casts shadows under brows, noses, and chins. Underlighting reverses these effects. Multiple lights create overlapping shadows and separate highlights. Colored lights tint the planes they reach and change local colors on skin, metal, and cloth.
Why it matters
Control over lighting setups keeps highlights, shadows, and color shifts tied to the light sources. Weak control can place highlights where light cannot reach, flatten forms during angle changes, or make a subject appear lit from inconsistent directions.
You can check it when
- ✓Name the main light directions and colors in your own paintings, and identify which planes each light reaches.
- ✓Redraw the same object under a different setup, such as changing top light to backlight, and check that the highlights and shadows change with the setup.
- ✓Show distinct contributions from each light source in scenes with multiple lights, including separate highlights and overlapping shadows.
- ✓Use strong colored light while keeping materials identifiable and matching color shifts to the light source.
